According to the Sun, there's four Premier League clubs interested in Allen's services as well as one La Liga outfit who could look to buy the midfielder, who arrived at Liverpool from Swansea for £15m in 2012.

Allen has a chance to impress Klopp before the end of the season with captain Jordan Henderson ruled out for the run in, and he played well in his side's demolition of Stoke on Sunday.
